GEXEEAL KEY TO THE GAIIOPETALOUS OfiDEES 3 



■1- -i- 0\;iry few-ii vera! -celled, with solitary o\'ules in the cells, usually only 

 one maturing into a large bony-coateil seed in a fleshy pericarp. 



53. SAPOTACE.E. Shrubs or trees, mo.-tly with milky juice and alternate simple 

 leaves. Flowers small, hermaphrodite, tetra-heptamenms. Calyx and cijioUa much 

 imbricated in the bud ; the latter often bearing accessory lobes or appendages within, 

 sometimes petaloid staminodia also. 



*"=**# ()\dry inferior or superior, few-several-celled: cells of the fruit 

 one-seeded : stamens at lea^t twice as many a> the petah or lobes of the 

 corolla, sometimes indefinitely numerous and borne on or united with their 

 base or tube : flower^ reg'ular : shrul>j or trees, with simple alternate leave-, 

 sometime^ a resinous but no milky juice. 



54. EBEXACE^E. Flowers dioecious or polygamous; the male ones polyandrous. 

 Ovary superior and corolla hy|"it.vnous. .Styles as many or half as many as the 

 cells of the ovary, distinct or partly united. Fruit fleshy, containing,' solitary or few 

 large seeds with bony testa and cdrtilagiinais albumen. 



S.5. STYRACACEJJ. Flower- hermaphrodite, nearly pentapetalous and a numerous 

 cluster of stamens adnate to base of each petal, or more gamopetalous and the fewer 

 stamens monadelphous in a siiigle series. Style and stigma entire. Corolla epigy- 

 nous, in Sffirax peri^'ynous. Fruit dry or nearly so, one-four-seeded. when dehiscent 

 the seed bony : albumen fleshy. 



****** Ovary or gynoecium superior, dicarpellary, or in some monocar- 

 jiellary. very rarely tri-pentacarpellary. sometimes appeariiiLi to be tetra- 

 carpellary by the divi^ion of the two ovaries : stamens borne on the corolla 

 (in apetalous OleacecB. &c.. on the receptacles alternate with its divisions 

 or lobes, of the lame number or fewer. 



-i— Corolla not scarious and veinless. 



■w- Eegular with stamens fewer than it> lobes or petals, or no corolla : style 

 one : seeds solitary or very few. 



s 1. OLEACILE, Trees or shrubs, with opposite (rarely alternate) leaves : no stipules, 

 no milky juice. Stameii; usually two, alternate with the carpels ; these two-ovuled, 

 or sometimes four-ovuled : seed mostly solitary, albuminous. Forestiera and part uf 

 Fraxiaus apetalous and even achlamydeous. 



•w- -i-i- Corolla regular and stamens as many as its divisions, five or four. 

 = Ovaries two (follicular in fruit) ; their -tigma^ and sometimes styles perma- 

 nently tinited into one : plants with milky juice : flowers hermaphrodite : 

 leaves simple, entire. 



ST. APOCYXACEJl. Stamens distinct, or the anthers merely coimiveot or lightly co- 

 hering : pollen ordinary. Style single. 



8S, ASCLEPIADACEJi, Stamens monadelphous and anthers permanently attached 

 to a large stigmatic body : pollen combined into waxy pollinia or sometimes granu- 

 losa masses. Carpels united only by the common stigmatic mass.
